Abstract (in english)
   Weathered Tertiary coal (oxihumolite) from the Vršany mine is used to produce humic substances, derivatives of humic substances (fertilizers), humic acids and their salts. The content of humic substances in raw material average 28 per cent. To produce humic substances, the weathered coal is leached by sodium hydroxide and the alkaline extract is either used in aqueous form or dried. Additionally, the extract is used as a raw material for the production of fertilisers. Humitane N (liquid organo-mineral nitrogen fertilizer) and Humitane PK (organo-mineral phosphoric-potassium fertiliser) are the main commercial products. Humic acids and their salts are produced by purification and acidification of the solution containing humic substances
